Convolutional Codes

Convolutional codes are a type of error-correcting code used in digital communications to improve data reliability. They work by processing data through a series of shift registers and combining bits with mathematical functions, creating redundant information. This redundancy allows the receiver to detect and correct certain errors caused by noise or interference during transmission. Unlike simple parity checks, convolutional codes consider sequences of bits over time, providing more robust error correction for real-world communication systems like satellite links and mobile phones, ensuring messages are accurately received even in challenging conditions.
